T0 rtZZ whomjt may concern:

Be it known that I, LoUIs M. HooPER, a citizen of the United States, and a resident of Rutherford, in the county of Bergen and State of New Jersey, have invented a new and Improved Pump VVatenOloset, of which the following is a full, clear, and exact description.

My invention relates to an improvement in water-closets of that type in which a handoperated pump is employed to discharge the same, said type being generally termed marine closets because they. are principally used aboard vessels and in situations where gravity discharge cannot be employed.

My invention comprises certain novel parts and combinations of parts, which will be more particularly pointed out in the claims.

The drawings accompanying herewith represent my invention in the form which is at present preferred by me. p

Figure 1 is a top plan view of the closet. Fig. 2 is a sectional elevation looking from the front. portion of the water-supply passage to the Fig. 4 is a side elevation looking from the left of Fig. 1. Fig. 5 is a front elevation of a slightly-modified form of closet. Fig. 6 is a side elevation of the form Fig. 7 is a section of the pump-operating lever, showing a means employed for opening the water-supply Valve. Fig. 8 is a vertical section through the discharge-pump. Fig. 9 is a section through the water supply Valve. Fig. 10 shows a modified form of device for opening the water-supply valve, and Fig. 11 shows one of the hinges for the closet seat and cover.

The usual practice in marine water-closets is to employ a pump by which Water for flushing the bowl is supplied and another pump of larger capacity for discharging the contents of the bowl, this last pump discharging through the side of the vessel. This plan is here adopted, the pump M being the flushing-pump and I the discharge-pump. The

- discharge-pump is connected with the bottom of the bowl by a pipe H, which has a checkvalve g therein, preventing water flowing from the pump back into the bowl. Any

Fig. 3 is a rear elevation with a' form of check-valve may be employed. I have shown an ordinary flap-valve; but the mounting thereof and the manner of putting it in place is novel. The valve is pivoted upon a ring G, which'acts as the seat and fits within a groove it, formed within the pipe H and opening through the upper side thereof. This groove above the center line of the pipe has straight or tangential sides, so that the ring G, with the valve'attached, may be slid into place from outside the pipe or removed without disturbing any other part of the device. The ring should fit closely in the groove, so as to form a tight joint. The upper side has flanges g extending over the top of the pipe beyond the edge of the groove and is secured in place by screws passing through this flange or by any other means. The pipe H is secured to the bowl by a method which is simple and eflicient and which permits the connection to be made either to the right or the left, as desired. In the bottom of thebowl is a hole passing entirely through it and of a size to fit the said pipe. Thepipe is provided with an opening on one side communicating with the bowl and with flanges l1. and [L2, adapted to engage opposite sides of the how] about said opening, one or both of said flanges being adjustable, so as to clamp the bowl-base between them. Flange 7L is shown as in the form of a cap which screws upon the pipe. If packing [L3 be interposed between flange It and the corresponding flange 7&2 of the cap and the cap screwed up, a tight joint will be made, and the pipe may extend in either direction from the bowl. The discharge-pump cylind erI connects directly with the pipe H. The piston J in the form shown has an inlet-hole therethrough and a ball-valve K, which is retained in place by the arms of the piston-rod, which are connected with the outer portions of the piston. A ball-valve K is also employed for the discharge from this pump. The discharge-pipe L is conducted in any'direction desired. The particular form of pump-piston and valve employed, however, forms no part of my present invention. Other forms might be used.

In connection with the discharge-valve K I have shown a threaded stem 7 which may be screwed down upon the ball K so as to force it upon its seat and then prevent the possibility of leakage when the closet is permanentl y or temporarily thrown out of use.

The flushing-pump M may be of any desired construction, but should be of less capacity than the discharge-pump. Its discharge-pipe m connects with the closet-bowl after the man ner shown in Fig. 3. same as described for the connection of the pipe H with the bowl. A boss or projection is formed on the back side of the bowl, within which is the discharge-passage B, and through the lower end of this boss is formed ahole for the reception of the pipe 711., which pipe is cut away on one side, so as to communicate with said passage B. Packing-washers with clamping-nuts m m are placed upon the pipe. The greater part of the water-supmy passes by the opening or port 7) into the flushing-channel 7), which extends about the bowl within its rim, and discharges by frequent openings into the bowl, as shown in Fig. 2, the same being the usual construction. Part of the water, however, passes through openings (/3, which connect with the refill-chamber a, which is also located in the rim and which communicates with the bowl by one or a small number of holes, as a. 1 have shown two such holes in Fig. 2. The capacity of these discharge-holes being much less than the supply-holes (4 the refill-chamber will fill while the pump is beingv operated and will then slowly discharge its contents into the bowl, thus supplying the water which it is desirable shall always remain in the bowl. It will be noticed that the refillchamber is independent of the passage through which the water for flushing the closet passes and that therefore flushing commences immediatel y instead of being delayed until the refillchamber is filled. This is an important feature.

The pumps are operated by means of a lever 0, which is inserted in a socket and pivot member P, pivoted at p. Arms P extend therefrom upon both sides of the pump I and are connected, through a yoke-shaped link N, with the piston-rod of the discharge-pump. An arm n connects the discharge-pump piston with the piston-rod of the flushing-pulp p, so that both are operated together. Thearm 11, Figs. 1, 2, 3, and 4, is secured to the rod of the discharge-pump and is adapted to rock slightly where it is connected with said pistonrod. The arm a being carried on the pistonrod of the main pump does not rock.

Between the water-sup ply and the pump M is placed a valve R, (see Figs. 3, 4, and 6,) which is normally closed and prevents water leaking into the closet-bowl. This valve must be opened. before the closetcan be flushed out. A preferred form of valve for this purpose is shown in detail in Fig. 9. The water-su1i)ply is connected at rand the discharge at r. Two

This is substantially the combined.

valve-seats R R with two valves V and V, are used. Thestem S of valveVextends outside the case at one end. These two valves are not secured together; butvalve V is adapted to engage and lift valve V. Ordinarily, however, there is a little play, so that valve V will not lift until after valve V has slightly raised. Each valve is independently held upon its seat, valve V by spring S and valve V byspring S Bythe use of the two valves independently seating a double security against leakage is provided. Both valves are not likely to leak at the same time. It is evident that more than two valves might be thus 1 have provided means whereby these valves may be opened either by the action of the pump-operating lever or by an auxiliary lever or catch carried by said lever. Fig. 7 shows in detail one form of device for this purpose. (Illustrated in Figs. 5 and 6.) The lever O is made tubular and has a trip or auxiliary lever a" mounted thereon, so that it may be grasped by the hand when taking hold of the handle of the lever 0. One end of the trip-lever extends within the tubular lever O and is connected by a link (2 with a rod or bar a, which is guided in the lower end of the tube 0 and has its lower end projecting from or capable of projecting from the tube. This rod 0 is normally held raised or retracted by a spring '0, but is projected by the action of the trip-lever a, so as to engage one end of a lever U, the other end of said lever being in position to engage the stem S of the supply-valve to open it. The other form of operating device shown in Figs. 1, 3, and 4 is shown in detail in Fig. 10, in which the lever O is pivoted in the upper end of the socket or pivot member P upon a pivot 79, which is at right angles to the pivot 11. The lower end of the lever O is shaped so that it may have a limited rocking movement upon the pivot 72. In one of the pivots p is placed a pin or rod T, which is forced inwardly or against the end of a lever O by a spring t. The outer end of this pin or rod T is in position to engage the lever U by which the valve R is opened. When, therefore, the lever O is swung to one side, it will open the supply-valve and then when swung back and forth on the main pivots 7) will operate the pumps, the valve R being held open as long as the lever O is held in such position as to keep the pin T projected.

It is evident that the means employed in carrying out my invention may be widely changed in form without departing from the spirit of my invention. I do not, therefore, wish to be understood as limiting my invention to the means herein shown, but to claim any means which are substantial equivalents of those shown. The scope of my invention is to be determined by an inspectionof the claims, in which the omission of any element or qualificationof an element is to be understood as a distinct statement that such element or qualification is not essential in that particular combination.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. In a water-closet the combination with a pump for supplying the flushing-Water, and a pump-handle for operating the same, of a normally closed supplemental valve in the watersupply to said pump, and means for opening and maintaining open said valve during the pumping action, said means being operative from said pump-handle.

2. In a water-closet, the combination with a flushing-pump, and a lever for operating the same, of a normally closed supplemental valve in the water-supply to said pump, a valveopening member having connection with said valve and extending to substantially the pivot of said pump-lever, and means carried by said pump-lever for actuating'said member to open the valve.

3. In a water-closet, the combination with a flushingpump,'and a lever for operating said pump adapted to h ave a slight movement transversely of its pump-operating movement, of a normally closed valve in the water-supply for said pump, and connections for opening said valve by the transverse movement of the pump-operating lever.

4. In a Water-closet the combination with a flushing-pump, a lever for operating said pump, and a pivot member receiving said lever and permitting a limited movement of the lever transversely of the pump operating movement, of a normally closed valve in the Water-supply'to said pump, and a valve-opening member adapted to be engaged by the transverse movement of the pump-operating lever to open the valve.

5. In a Water-closet the combination with a flushingpump, a lever for operating said pump, and a pivot member receiving said lever and permitting a limited movement of. the lever transversely of the pump operating movement, of a normally closed valve in the Water-supply to said pump, a sliding pin mounted in the pivot-axis of the pump-operating lever, and adapted to be engaged and moved by the said lever, and a lever connecting said pin with the valve-stem to open it.

6. In a water-closet, the combination with a flushing-pump, and a lever for operating the pump of a normally closed valve in the Watersupply for said pump, a movable pin passing substantially through the axis of said lever, connections from said pin to the valve to open it and means carried by the pump-operating lever for actuating said pin to open the valve. 7 In a water-closet, the combination with a flushing-pump, and a-lever for operating the same, of a normally closed supplemental valve in the water-supply to said. pump, having a plurality of valves and valve-seats placed in series, a valve-opening member having connection with said valve and extending to substantially the pivot of said pump-lever, and means carried by said pump-lever for actuating said member to open the valve.

8. In a water closet, thecombination with a discharging-pump, a flushing-pump and a lever for operating said pumps, of a normally closed supplemental valve in the Water-supply to said flushing-pump having a plurality of valves and valve-seats placed in series and closing with the Water-pressure, one of said valves being mounted upon a stem and adapted to engage with and lift the other valve, and a valve-opening member engaging with said stem to open the valves and extendingto substantially the pivot of said pump-lever, and means carried by the pump-lever for actuating said member to open the valve.

In testimony whereofI have signed my name to this specification in the presence of two subscribing witnesses.
